Confirm the Output has a data size of 3 words and the Input has 4 words. This
is because P163 to P169 and P174 to P179 are all set to zero.
Note Do not set bit 15 of the Coil data 0 to ON. The operation status coil (000Fh)
cannot be used in the output process area.
Set A001 = 3 and A002 = 3 so that the Inverter can be controlled using the
Modbus registers in Flexible mode.
Set the Opr bit to put the Inverter in run mode. The RUN indicator on the
Inverter should light up at this point. If this is not the case, check your source
selection.
Change F001 in the Output data to the desired frequency (E.g. 1000 for
10.00 Hz)

The motor accelerates until it reaches the desired frequency. Notice that the
FA1 bit is set once the inverter has reached the desired reference frequency.
